This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Brachycentrus appalachia (Apple Caddis) Caddisfly Adult Pictures

The wings of this specimen were pale tan, almost white, when I collected it, and the body was of the lighter "apple green" from which this species gets its common name. Everything turned much darker by the time I got it home and under the camera.

The wings look even darker in some of these pictures because the background is black and the wings are unusually translucent. You can see that in one of the pictures where the body easily through the wings. They're really a light, translucent gray, which is still far from the pale tan of the same fly when it was freshly emerged.
